PEN-)I'POINT EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 665,383, dated January 1, 1901.

Application filed April 4, 1898. Serial No. 676,457. (No model.)

To all whom, it may concern:

Be it known that I, ANDREW J. DAVIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented or discovered a new and useful Improvement in Pen-Point Extractors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view showing my improved pen-point extractor grasped by the hand. Fig. 2 is a similar view showing it pivotally mounted. Fig. 3 is a similar view showing the device elevated to permit the ball to recede. Fig. 4 is a side elevation. Fig. 5 is a central longitudinal section. Fig. 6 is a plan view. Fig. 7 is an end view from the back.

My invention consists of an improved device for extracting pen-points from holders; anditconsistsofa tapered socket containing a hall adapted to bear against the pen-point and the opposite side of the socket with a retaining power in proportion to the degree of withdrawing strain exerted on the pen, whereby the point is drawn from the holder.

Referring to the drawings, 2 is a tapered shell, which may be circular or oval in cross- 0 section, as desired, within which is contained a ball 3, slightly larger in diameter than the width of the opening at the small end of the shell, while a turned-in lipt at the other end prevents escape or loss of the ball. Within 3 5 the shell the ball is free to move, and when the shell is tipped, so that the ball will roll toward the back end, a pen-point 5 may be freely inserted in the other end, and upon tipping the shell downwardly the ball will 40 roll down upon the point and wedge itself in position between the point and the opposite side of the shell. Outward strain on the point will tend to roll the ball forward, wedging it tighter, and such strain may be in- 5 creased until the point is drawn from the holder, when pressure toward the large end of the shell will instantly release it, when it may be removed. The shell is provided with a rearward extension 6, preferably somewhat 5o curved, which serves as a finger-piece by which the device may be held by the operator. It may also be pivotally attached to any permanent support, as a wall or side of a desk,by means of a screw 7,passing through hole 8, when it will be in a convenient position for ready use at all times.

While I have found good results with a circular-shaped shell, I prefer to make it somewhat ellipticalin cross-section, as shown on Fig. 7, thus permitting very wide or very narrow points to be inserted, the ball acting against the center of the point with equal force and effect.

My device is very efficient in operation and isvery simple and cheap to construct, and its merit and usefulness will be readily appreciated by all those accustomed to the annoyance of removing pen-points from holders, especially when fouled.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. A device for extracting pen points from their holders consisting of a tapering hollow shell having a larger and a smaller end, the wall thereof being substantiallyimperforate, a turned-in retaining-lip at the larger end of the shell, a stem extending from the larger end to constitute a handle by which the extractor is held in operation, and a spherical ball contained in said shell, said ball being slightly larger than the smaller opening of said shell so as to engage and securely hold the pen-point between it and the shell.

2. A device for extracting pen-points consisting of atapered hollow shell, elliptical in cross-section at its smaller end, a turned-in retaining-lip at the larger end, an extended stem formed integral with the shell forming a handle and a spherical ball contained in the shell and slightly larger than the reduced end, substantially as set forth.

3. A device for extracting pen-points, consisting of a tapered hollow shell elliptical at its smaller end in cross-section, and a spherical ball contained in the shell and slightly larger than the smaller end thereof.

In testimony whereof I have hereunto set my hand.

ANDREW J. DAVIS.
